Remember the "Agave" extensions for Office? If you don't, visit

If you've looked for them in the O2013 preview released today, you've probably not found them (I know I hadn't when I looked). To add an Agave add-in, Open a blank Word, PowerPoint, or Project document -> Ribbon "Insert" -> click the picture above "Apps for Office." Now just pick an app (which will open your browser), and press "Add." Go back to Word, PowerPoint, or Project and
click on "Office Store" in the Apps for Office window, then "Refresh" next to "Manage my apps." select the app you added, and double click it.
